G12 vs S100 Totally confused HELP

I am going to Italy in May & can not make my mind up between the S100 and G12.

What I am looking for is the ability to take good sharp photos in the auto mode as I am not that proficient in photography. I have held both cameras and like the feel of the G12 but I like some of the other features of the S100. Pocket ability is not an issue in choosing, I just want a camera that I will be satisfied with for the next year or 2.
PLEASE help me make up my mind.
